This document defines a new Port Control Protocol (PCP) [RFC6887] functional element: the PCP proxy. As shown in Figure 1, the PCP proxy is logically equivalent to a PCP client back-to-back with a PCP server. The "glue" between the two is what is specified in this document. Other than that "glue", the server and the client behave exactly like their regular counterparts.

                Port Control Protocol (PCP) Proxy Function


   This document specifies a new Port Control Protocol (PCP) functional    element: the PCP proxy.  The PCP proxy relays PCP requests received    from PCP clients to upstream PCP server(s).  A typical deployment    usage of this function is to help establish successful PCP    communications for PCP clients that cannot be configured with the    address of a PCP server located more than one hop away.
